Pyramids is a stereo flanging Device with five presets, eight flanger modes, tap tempo, tap subdivision via the Rate & Tap mini-toggle, a multifunction Modify control, positive and negative Feedback, and a variable Mix control, which is something you don’t see on a flanger every day.

Pyramids’ Classic Mode delivers the “classic” (duh) jet-plane liquid-silk flanging sound we all know and love and have come to expect from any reputable flanging Device. Try this mode to recreate the sounds of old-school ADT (Automatic Double Tracking) effects as heard on records by those loveable mop-tops from England (you know which ones) and on the most ripping riffs to come from the NWOBHM.

Try this one in stereo. In Through-Zero Mode, Pyramids gives you authentic tape-style flanging without all the calibration, biasing, demagnetizing of heads, and so on that a real tape machine - two of ‘em, actually - requires.

In Through-Zero Mode, the Modify control adjusts the delay of the dry signal and Manual controls the delay time of the wet signal. Experiment with these controls in unison to dial in the sweet spot for the dropout!

Barber Pole Up
“Barber Pole” flanging refers to an infinitely sweeping upward flange with no beginning, middle, or end. This, depending on your point of view, sounds either like Ms. Poppins taking flight with her umbrella, or a nightmarish Kafkaesque hellscape where time is meaningless and we spend the rest of our natural lives staring into the void, forever dwellers on the threshold.

Barber Pole Down
Barber Pole Down is exactly like Barber Pole Up, except the flanging effect goes downward in pitch, rather than upward.

Trigger Up
Trigger Up Mode is similar to Barber Pole Up mode, minus the existential dread. The flanger still produces a continuous upwards sweep, except in this mode, your pick attack (or pressing the Tap/Trigger Switch) re-triggers the flange from the beginning. It’s like getting a fresh start with every note! In Trigger Up mode, the Rate control adjusts how quickly the sweep reaches the top and Modify acts as a sensitivity control for the re-triggering effect.

Trigger Down
Trigger Down is exactly the same as Trigger Up, only the flanger sweeps downward. Cool, huh?

[Pro Tip: In Trigger Up/Down modes, you may re-trigger the flanger using an external source in what we call Side Chain Flanging. To trigger Pyramids using an external source, plug your primary instrument (the signal on which you want to hear the flanger) into the Right Input and connect Pyramids’ Right Output to your amplifier or DAW. Connect the external trigger source (drum machine, sequencer, etc.) to Pyramids’ Left Input. To hear only the affected primary instrument signal (as modulated by the external trigger source), do not connect the Left Output. Your primary instrument’s signal will pass through Pyramids’ Right Input / Output, but the flanger will react to changes in the external trigger signal instead of your primary instrument. To monitor the trigger source, connect Pyramids’ Left Output to a separate amplifier or DAW input.]

Step mode tries to restore order to the universe by sweeping up and down in stepped increments, kind of like the sequencer on a synthesizer. In Step mode, the Modify control adjusts the glide between steps. Low Modify settings produce sharp, stair-stepped transitions between steps. Higher Modify settings introduce a smoother glissando effect.

Random mode is like Step mode, except the sweep is randomized without reason or rhyme. Some men just want to watch the world burn.


Pyramids ships with five factory presets. Please feel free to store, modify, or overwrite these as you’d like!
